Breaking with tradition, UN Secretary-General Antonio Guterres has told country leaders not to come to the podium Monday without „concrete and transformative plans“ to halt rising global temperatures, achieve carbon neutrality and cut carbon emissions by 45 percent. VIPs with proposals have been told they have just three minutes to speak.

How concrete the results of the summit will actually be is unclear. The UN doesn‘t have a global climate army to roam the planet stopping pollution, so it‘s up to the 193 nations of the UN to take action.
